fix: standardize database credentials with environment variables and …

[thisisnkc]

Description

This PR refactors the test suite to improve reliability, maintainability, and developer experience. The changes address Node.js compatibility issues, centralize database configuration, improve test cleanup behavior, and standardize test naming conventions.

Summary of Changes

1. Fix Node.js Compatibility in File Driver

Fixed a crash in the file driver’s cache pruning logic when running on Node.js versions prior to v20.12.0.

Older Node.js versions do not expose the parentPath property on fs.Dirent objects, which caused path resolution to fail during pruning.

Before

const filePath = join(dirEntry.parentPath, dirEntry.name)

After

const basePath =
  typeof dirEntry.parentPath === 'string'
    ? dirEntry.parentPath
    : dirEntry.path

const filePath = join(basePath, dirEntry.name)

This ensures compatibility across all supported Node.js versions.

2. Centralize Database Credentials

Database credentials are now configured via environment variables instead of being hardcoded in individual test files.

Changes made

• Added centralized exports:

  • MYSQL_CREDENTIALS
  • POSTGRES_CREDENTIALS

  in:

  tests/helpers/index.ts
  

• Updated .env.example with all supported configuration options

• Refactored all database driver tests to import credentials from the shared helpers module

3. Improve Test Cleanup Reliability

Replaced manual disconnect() calls with Japa’s cleanup() hook to ensure resources are released even when tests fail.

Before

test('example', async ({ assert }) => {
  const connection = new Connection()
  assert.equal(...)
  await connection.disconnect()
})

After

test('example', async ({ assert, cleanup }) => {
  const connection = new Connection()
  cleanup(() => connection.disconnect())
  assert.equal(...)
})

---

4. Standardize Test Group Naming

Applied consistent sentence-case naming conventions across all test groups.

Examples:

• Redis driver
• Knex | Postgres driver
• Kysely | Mysql driver

---

Outcome

• Improved Node.js compatibility
• Centralized and configurable database setup
• More reliable test cleanup
• Consistent and readable test naming
